provide the arm E with an angled plate E2 which enbers coiled springs K3.' A plate L has at the top a' flanged portion L sliding on the side members of the bail K and carrying at its lower end downwaidly and forwardly projecting lugs L2 between which are journaled a roller Lfs which engages the rail J. A plate.

L is permitted a slight upward movement, the iiange L sliding upon the bail K `but at the same time exerts a sufficient pressure upon the rail J to bring the Contact plates .l4 and J5 into engagement with each other. In order that the-red light may be shown I gages the angled end D2 oi the arm D.

The electric circuits yare as ollowsz--Batteries M are placed in'the casing A and a wire 3 leads to the incandescent lamp C2 and to the Contact plate l. A wire'4 leadsfrom the batteries to the contact` point 2. It. will be obvious that whenever the arm E is drawn into the horizontal position for the purpose oi attaching a mailV bag thereto and thereby depresses the contact plate l bringing it into engagementvwith the contact point 2, that 'the lamps C2 will be thrown into circuit with the batteries A wire 5, also leads from the batteries through the electromagnets H3 to the contact plate J anda wire,6 leads from the batteries 'to the plate J The operation of the device Ais as follows-The lever H is swung around until it engages the hook end of the 'y lever II" thus swinging the post B and winding the spring .G. This will throw the arms E and E in a posiltionparallel to-the track when the mail bag has been attachedthereto.- As soon as the arm E is drawn downward for the purpose oi hangingr the mail bag thereon the circuit will be completed between the batterics'M and' the' lamp C2 and the plate E2 by engaging the angled-'end D2 of the arm D will throw the red disk D into alinement with one of the light openings (V, 'lhe device will remain in this position untita roller L3 carried by a'inail train depresses the adjacent rail J and thereby completes a circuit i'rom the batteries through the wire 5 and magnets Il, contact plates J i and .l5 and wire 6. As this energizes the magnets II:i the armature H2 will be lifted thus lifting the end of the lever I-I which'is engaged by the armature and depressing the hook end thereby releasing the lever 1l, ad as soon as said lever is released the spring G will swing the post one-fourth oi a revolution or back into the position occupied by it before the lever had iir'stbeen moved thus bringing the mail bag into position to be grabbed from the'inail car and also displaying the red danger light.

Cri

As soon as the bag F is caught by the car the arm E will swing into a vertical position and the arm E will drop also to a vertical position, lasp's common in such arms.-

This movement oi the arm lil will break the circuit bev be employed in the lantern boxes (l so that a Whitelight will show at all times through the night excepting when the arms are swungT at right angles to the track and carrying an undelivcrcd mail sack. But should the Inail car fail to catch the sack from the arms they will remain in the position in Fig. 3 and the red light will be displayed thus warning the engineer oi any iollowing mail train and also the mail clerks that they are approaching a mail sack which had been left by the preceding train.

Having thus ully described my invention, what I claim as new and desire to secure by Letters Patent, lSI- 1. A device of the kind described, comprising a rotatn hie post, pivoted arms carried by said posi, means for roiatingthe post to thrw the arms at righi' angles io :i track, und an incandescent lamp, the lamp circuit being completed when the arms are parallel io each other.

2. A device of the kind described comprisingy a rotatable posty upper and lower arms connected thereto for supportingl a mail sack, means for locking the post against rotation, means for autonmticnlly releasing' the post and givingl the same a one-fourth revolution at. a predetermined |time, a signal lamp adjacent the upper arm, and means for lighting said lamp when ine arm is in un operative position.

Ii. A device of the kind described comprising' a post, pivotcd arms carried by the post ior supporting,y a mail bag, a signal lamp ci ried by the post, a swingingl arm bearing a transparent tinted paneisaid arm being angled, andan angled plaie carried by thc arm'to' engage the angled end 'ot' the swinging arm and throw the panel into aljnement with the la mp.

4. A device of the kind described comprising n rotntav hie post, arms carrieihthereby, a springl adapted to rotate the post in one direction, n lever carried by the post for rotating the same'in the opposite direction, locking mechanism ladapted to be engaged by said lever, releasing means included in an electric circuit normally open und means carried by a mail train for .completing said circuit.

Vi. A device of the kind described comprising a rotatable post, n signal lump supported by the post, batteries in circuit with said'lamp, the circuit being broken at the top 'of the posi, an nrm i'or holdingl a mail sackl pivotally cnrried by the posi, the said circuit being closed when the arrn is thrown inio u horizontal position und means for automaiicaily rotating the post and throwing the said arm into a position at right angles with respect to a truck upon the approach of the mail train.

G. A device of the kind described comprising a rotatable posi. a signal light carried thereby, va mail sack holding,r arm pivoiaily carried by the post, -ah electric circuit including' the signal light, said circuit being automatically closed when the arm is thrown .into operative position arid broken when the arm falls into inoperative position, an arm carryingl a disk formingl u danger signal adapted to register with the signal iight the last mentioned arm being engaged and brought into upright position by the iii-st mentioned arm; and means for automatically'throwing the iirsi. mentioned arm at right 4angles to a track and bringing' I the danger signal into view ot' an approaching train at n predeterminedtimev 7. A device of the kind described comprising a rotatu ble posi, suck holding arms carried there'by, a level' connected to the post, u spring encirciini.,r the post and havlngione end hearing upon said lever, a lever provided with a hook en'd adapted io engage the iirst mentioned level', an armulture adapted to trip the lust mentioned lever sind release the lever carried by the post, electro-magnets for attract:- ing the armature, an electric circuit including said mugneis, said circuit beingl broken at a point.' adjacent a raliway track, contact points arranged adjacent said truck, and menus carried by a movingl train for bringing said contact 'points igethcr thereby: closing the circuit.

8. A deviqeot"v the kind described comprising rotatable post, pivoted arms carried thereby, a signal light carried thereby, a spring adapted to be wound by rotation of the pqst in one direction and to rotate the postupon nnwinding, 21 lever carried by the post, a plvotcd lever adapted to engage the one lll-st mentioned and lock the post against rotation by the spring, electrically operated means for tripping dang-er signal, said signal being engaged by one of the arms when thrown in the operative position bringing the danger sig-11:11 into-alinement with the signal light :1nd holding it tllcre, nn electrical circuit including the signallight, said said inst mentioned lever, a transparentv I circuit being; completed when the arm lastmentioned is in- 10 operative position, un electric-nl circuit including the lever tripping means and broken adjacent a1 track, and means arranged in part adjacent the track and in partcarried liy a train for completing the last mentioned circuit.
